Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-16 Unimplemented: Read as ‘0’

bit 15-10 BMXDUDBA<15:10>: DRM User Data Base Address bits

When non-zero, the value selects the relative base address for User mode data space in RAM, the value

must be greater than BMXDKPBA.

bit 9-0 BMXDUDBA<9:0>: Read-Only bits

Value is always ‘0’, which forces 1 KB increments

Note 1: At Reset, the value in this register is forced to zero, which causes all of the RAM to be allocated to Kernel

mode data usage.

2: The value in this register must be less than or equal to BMXDRMSZ.
